Bill Cosby's lawyers are fighting to let jurors at his sexual assault retrial hear from a woman who says accuser Andrea Constand talked about making up allegations so she could sue and get money.
Lawyer Becky James argued at a preliminary hearing on Thursday that Marguerite Jackson's testimony shows Constand's state of mind before she went to police with allegations Cosby drugged and molested her in 2004.
Constand's lawyer has said Jackson is "not telling the truth."
Jackson worked with Constand at Temple University.
Jackson says Constand talked about wanting to set up a "high-profile person" after seeing a television news report about a celebrity accused of violating women.
Prosecutors say Judge Steven O'Neill should block her testimony like he did in the first trial because it would be hearsay.
